Our industrial telephones are protected by a weather-resistant metallic powder coating—a resin-based material that is electrostatically sprayed and heat-cured to form a dense, uniform layer on metal surfaces. Unlike liquid paint, it provides superior durability and environmental protection without VOCs.
Key advantages:
Weather Resistance: Resists UV, rain, and corrosion.
Durable & Scratch-Resistant: Stands up to impact and daily wear.
Eco-Friendly: Contains no volatile organic compounds.
85% spare parts are produced by our own factory and with matched test machines, we could confirm the function and standard directly.
